Working in Greenwich

We work right across Greenwich — SE3, SE7, SE10 and 1 more postcode districts — and in neighbouring Blackheath and Canary Wharf.

London homes in Greenwich often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If your Greenwich house has a combi boiler, a loft shower can usually run on mains pressure without a pump. If your Greenwich loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.

Most of Greater London has very hard water. If your supply in Greenwich is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

A survey of the headroom across the room, with the usable height marked at each fitting position
Fitted furniture made to the eaves, so the low space behind the slope becomes storage
A check of the floor joists where a bath or large shower tray will sit
Electrics by a qualified electrician, tested and certified, then tiling, testing and handover

Decisions to make first

Roof window

A roof window over the bath or shower brings daylight and fresh air, but plan the blind for privacy and expect condensation on cold glass.

Bath or no bath

A bath under the slope makes good use of low space, but the floor has to carry it when it is full of water and someone is in it.

Rules that apply in England

In England, new drainage and a new connection to the soil stack fall under Part H, a new bathroom needs extract of 15 litres per second intermittent or 8 litres per second continuous under Approved Document F, and new circuits are notifiable under Part P. If the work includes an unvented hot-water cylinder, it must be fitted by a G3-qualified installer.

Loft bathrooms in Greenwich: questions

How much should I budget for a loft bathroom in Greenwich?

A loft bathroom in Greenwich usually costs £8,100–£16,250 including VAT. Room size, layout changes and your choice of products move the figure within that range. The free survey gives you an itemised quote, fixed in writing once the details are agreed.

Is the water hard in Greenwich?

Who handles building control for a loft bathroom in Greenwich?

Building control for Greenwich is handled by the local council or an approved inspector. If your job needs sign-off — for example a new circuit, new drainage or a new extractor where there was none — we tell you at the survey and handle the notification as part of the work.

How long does a loft bathroom take?

Allow 6–12 working days on site for most jobs, plus the lead time for products after you approve the quote. We give you a day-by-day plan before work starts in Greenwich.

Is a bath too heavy for a loft floor?

A standard acrylic bath is usually fine on a loft floor built for a conversion, but a filled bath with someone in it is heavy, and stone-resin or cast-iron baths are much heavier still. We check the joist size, span and direction at the survey, and a heavy bath may need a structural check and strengthening first.
